android日历应用内默认铃声和实际听到的铃声不一致问题

1.首先在类 frameworks/base/media/java/android/media/MediaPlayer.java 的setDataSource方法内对当前播放的uri进行打log，打了log之后就知道了当前播放的uri（与默认铃声不符的铃声uri），添加判断uri为当前播放的uri的话，就将默认铃声设置进去

 public void setDataSource(@NonNull Context context, @NonNull Uri uri)
             throws IOException, IllegalArgumentException, SecurityException, IllegalStateException {
   //add start
   String str = uri.toString();
   if (str.equals("android.resource://com.google.android.calendar/raw/timely_event") ) {
           Uri muri = RingtoneManager.getActualDefaultRingtoneUri(context,RingtoneManager.TYPE_NOTIFICATION);
        setDataSource(context, muri, null, null);
    } else {
        setDataSource(context, uri, null, null);
    }
    //add end
}

2.还要在vendor/mediatek/proprietary/packages/providers/MediaProvider/src/com/android/providers/media/RingtonePickerActivity.java 内的onPrepareListView（）方法内添加

//add start
String str = mExistingUri.toString();
if (str.equals("android.resource://com.google.android.calendar/raw/timely_event")) {
    int mClickedPos = getListPosition(mRingtoneManager.getRingtonePosition(                                
        RingtoneManager.getActualDefaultRingtoneUri(getApplicationContext(),mType)));
        setCheckedItem(mClickedPos);
}
//add end

注：文中出现的：android.resource://com.google.android.calendar/raw/timely_event  是我打log和默认铃声不对的资源，你们要打将uri打log，在铃声响的时候看log里面是那个，再将log打出来的uri替换掉android.resource://com.google.android.calendar/raw/timely_event的位置，才能实现出现的铃声就是默认铃声的效果
